To .all whom t may concern.: y l

v Be it lmown that I, DANIEL J. OROURKE, a citizen of the United States, k,residing .at Clarkdalre, in the 'county of-Yavapai and VState of Arizona, have invented. certain new and useful Improvements in Tool Supports, of which the following isa full, clear, and 4exact specifica-tion. I

My invention relates to tool supports. It has for its object to provide an improved and simplified adapted to permit a wide range of adjustment of the tool in ysuch a manner that .the latter is enabled to drive holes disposed at widely .different angles. A further object `of lmy invention is to provide an improved, simplified and lightened tool support espefcially adapted to use in quarries or the like in lieu of the usual cumbersome and expensive gadder frames, in breaking lines in marble or other stone, the same being so adjustable that a hole may be :driven atany desired angle. yThese land other. objects of myfirlnprovement will, however, hereinafter more'fully appear.

In kthe accompanying drawings, I have yshown for purposes Voil `illustration one. emllxvodiiment'which `my invention 'may assume in practice.V y y In these drawings, r Fig. l is :asi-de' elevation of my :improved 'sumuortfwit'h its tool at'worlr upon a verti- Figi@ is aside elevationotthe same, .a-

portion ofthe face being shown in section to Iillustrate certain drilled holes.' Fig. is an enlarged detail verticalfsectional' view showing the-mounting of 4the swiveled frame. i lj l Fig. ltis la 4similar transverse sectional view taken on line 4-410 Fig. 3. a

Fig, '5 is adetail view partially in section showing theswiveled mounting of the tool.'

While the invention ma?)vr be used with a Vtool ofany desired: ytype,"`in 'thisyillustrav tive construction I have shown-the :same as These means includeva suitable base or tool support which mounting, herein shown as preferably' comprising a tripod having independently .adjustable, preferably weighted, legs 3 adjustable about a horizontally disposed upper pivot member 45,'the upper end 'of therear leg 3 being bifurcate-d and disposed onL said member/JC 'between the upper ends `ofthe other legs, as in a usual construction. As shown,a tool carrying bar 5, preferablyiof tubular stock., is connected thro-ugh suitable brackets `adjacent its opposite ends,lwitha plurality of 'oppositely extending -angularly disposed, and preferably tubular, stay rods 7 cooperating therewith to `form a truss-like construction and having their inner ends attac'hed ata ypoint in rear :and adjacent-the middle of the bar 5 to a swivel member lor hub8, which -is in turn swiveled within swivel forming flanges 9 of a suitablesleeve l0. This sleeve 10 is, in'turn, carried on the;

member 4, and adapted to be clamped in a given position thereon by means-,oan adjustable clamping member 11 which Yoverlaps one edge of Ythe swivel 8 .and itself clamped-@position :on the Vmelnlre-VIO by means Iof a clamping `bolt l2 'having nlug or shoulder portion 13 on its lower-.end fengageablef with suitable projectionsll. on the memberl whenthe nut 15 on the r:upper 'end of the bolt istightened. Thus, it ywill be observed'thait the bar=5 is mounted in .a

swivelmounting in such a manner that, .when the boltlis released, the bar maybe notated inthe vertical plane shown in Fig. :1, about the bearingscarried on'the tripod. Attention Vis :also directed to the fact that by :swiveling the sleeve l0 in '-.suitable bear- ;ingslfonned on the biurcated upper end 'of the leg .3, the bar v5 may also be adjusted Vin another vertical planedispo'sed substan tially at rightvangles to the lfirst plane, the bar, as shown herein, being v'freely adjustable `rto the right `or left of theiposition shown in Fig 1,l by simply lloosening-.one or'more i nuts ll' which, in va Vpreferred construction, 'al'solserve toxcliamp the legs of the 'tripod to the memberlfl. .It will alsobe observed that the 'drill is herein provided'witha suitable .swivel-mounting 1.8 -in a supportingbracket 19 carried on the bar 5, the .construction thus being such that in' any ofl `the diilerent positions of adjustment of vthe bar 5, 'the drill l may be adjusted zangularlyfrelative to the bar. As shown, the drill is .also

'adapte'd'to be clamped in its. several posi' lio tions of adjustment by means of a clamping member 20 in turn clamped in position on the bracket 19 by a clamping bolt and nut connection 21. It will also be observed that to permit of even further flexibility, through the provision of a suitable longitudinally disposed groove 22 in the bar 5, and a cooperating spline 23 carried upon the bracket 19, both this bracket and the drill l may be bodily adjusted as desired longitudinally of the bar 5. j A

A s a result of my improved construction, it will be noted that an operator is enabled to drive a hole at any desired angle. For instance, the` bar 5, through one of its swivel connections, is adjustable in a vertical plane, and, by reason of its other swivel connection, is also adjustable in another vertical plane disposed substantiallyat right angles tothe first plane; while the drill, due to its own swivel mounting, may be adjusted into Yany desired angle relative to the bar 5 in a plane parallel to one of these planes, and, dueto its slidable bracket, if desired may be adjusted longitudinally of that bar in any position of the latter. Further, it will 'beobserve-d that through the use of a tripod type of base, the support may be even further adjusted and at the saine time adapted to use under widely varying conditions. Attention is also directed to the fact that iii my 'improved construct-ion the support, while possessing greatvstrength and suiiicient rigidity to withstand the strains and vibration encountered under service conditions, is at the same time of an exceedingly light type enabling the operator to make the desired adjustments with great facility, all

necessity for the provision of such heavy and lcumbersome supports as the gadder frames heretofore used, being thus eliminated. It will also be noted that due to my improved construction it is possible to produce a support having the great flexibilityof adjustment brought out above, at materially less expense, the construction being 4of a type which enables the support to be very cheaply and readily manufactured. These and other advantages of my improved construction will, however, be clearlyv apparent to those skilled in the art.

While I have in this application specifically described one embodiment which my linvention may assume in practice, it will be understoodl that this form of the same "is used for purposes of illustration and that the invention may be modified and em' i bo-died in various other forms without de- L parting from its spirit or the scope of the appended claims.
